"A security advisory (TALOS-2019-0857/CVE-2019-5068) found that
creating shared memory regions with permission mode 0777 could allow
any user to access that memory. Several Mesa drivers use shared-
memory XImages to implement back buffers for improved performance.
This path changes the shmget() calls to use 0600 (user r/w).
Tested with legacy Xlib driver and llvmpipe."
The intel driver can be used with inteldrm on ivy bridge or newer.
The radeon driver only works with amdgpu not radeondrm.
As we can't use python in xenocara add phony targets to create the
same output as python scripts which create json files for the loader.
This is just the ICDs, to use vulkan the loader and additional ports
are required.
ok mpi@ on an earlier version. Changed to call shm_unlink()
directly after shm_mkstemp() as suggested by kettenis@
drm render nodes have the same major as drm primary devices but offset
the minor by a base of 128.
I expected the name of the device to have numbering starting at 0 when
these non-linux codepaths were added (before we had render nodes).
* XKB-Config(7), XKB-Enhancing(7): user-level documentation
for XKB configuration; not perfect, but the best available.
* xtrans(3): a library actively maintained upstream.
* libXmu and libXext: Many libraries are effectively frozen upstream.
According to matthieu@, the documentation of libXmu and libXext
is among the most valuable of those.
Feedback and OK matthieu@.
Unlike linux our primary "drm" device name is substring of the "drmR"
render node device name and strncmp() tests resulted in render nodes
being flagged as primary nodes.
shared libLLVM are in base. And now we can finally build the radeonsi
Mesa driver adding accelerated support for radeon parts based on the
Graphics Core Next (GCN) architecture which is everything since
GFX6 / Southern Islands.
This can later be expanded to other architectures which build libLLVM
and have clang as the default compiler (to handle LLVM's c++11 headers).
